I do not believe there is a "official" size for the Sosa bat or the chilli pepper. These were never really "released". The chilli pepper I have is cedar wrapped and is a bit different form the one you have pictured. Or, it could just be the photo. The tip on mine is not quite as "sharp". There were two different sizes of the Sosa bat produced, if I remember right. They were also given out with the band on different ends, depending onw hen they were handed out. I bought both the chilli pepper and the Sosa Bat that I own, in March of 2001 at a charity herf, in Minneapolis. Along with those two I also got a Cuban Tickler. there was also an "A" that was called a Shark "A". I aquired that one in 2003 from the getleman who won it in the auction in 2001. Not sure of the exact production of these, but it was prior to 2001. I would guess they were given out to some people at the CFC in 2000.
As far as the maduros go, there are maduros of every production sized Opus X floating around out there. I had a Perfecion X and a xXx that were given out at the Fire Pit Crew Summit in 2001 (I think). I have also had double coronas, phantoms and I think a #5, at one time or another. Hard to say when any of them were rolled.
